Abstract :
In WCDMA [3 GPP G. T. 25.211, 1990], downlink channel indicators are used in a variety of procedures related to access and paging. A binary indicator is sent on the paging indicator channel (PICH) in a mobile station (MS) is paged. A ternary indicator is sent on the access indicator channel (AICH) when the MS attempts to access the network. While underlying motivations for using paging and access indicators are different, they both share same key performance aspects: detection reliability at the cell edge and downlink capacity consumption. This paper details a framework for PICH and AICH performance analysis. Results are derived that are of practical interest to the network operator for downlink transmit power budgeting.
